Office 365 user monitoring
A week before resigning, an employee downloads 2,000 sensitive files to a personal drive. In native logs, it looks like normal work. In 1Security, itâs a red flag. Fragmented signals often stay hidden until panic sets in. 1Security turns scattered activity into a clear narrative, helping teams spot risky exit behavior and prove control. No more guessworkâjust answers.
What is the challenge?
Doing It with 1Security
Stop analyzing rows. Start seeing the story. 1Security reimagines Office 365 user monitoring by connecting dots that native tools leave disconnected.
Unified activity view
Combine Entra sign-ins, Exchange actions, SharePoint and OneDrive events, and admin changes in a single feed that is easy to filter for investigations and audits.
Behavior-based alerts
Detect Intent, Not Just Events - like impossible travel or a sudden spike in external sharingâand get alerted with the full context attached.
Privileged change tracking
Track admin role grants, mailbox delegation, and SharePoint permission shifts so you can prove least privilege and spot abuse quickly across the tenant.
External sharing visibility
Instantly see when users create sharing links or invite guests. Know exactly what content is leaving your tenant and verify if itâs business-critical or just a lunch menu.
Plain-language reporting
Generate reports for security, compliance, and managers that explain activity and risk in plain terms, with exports ready for auditsâno PowerShell required.
Retention-friendly evidence
Keep a consistent history of key user actions and admin changes so you can answer who did what and when, even months later, without rebuilding timelines.
Copilot readiness checks
Validate what Copilot and other AI assistants could surface by auditing overshared content and risky access paths tied to real user behavior before rollout.
Solving It with Other Methods
Most teams assume that because they have logs, they have answers. In reality, native tools give you millions of isolated data points but zero narrative. This âDIYâ approach creates a dangerous false sense of security.
